Abstract

This study investigates Ohm’s Law through systematic experimental procedures involving various resistance configurations. The primary goal is to verify the linear relationship between voltage and current in resistors and their combinations, and to analyze resistance behaviors in series and parallel circuits. Data are collected and plotted to demonstrate the proportionality, and the resistance values are derived from the slope of the voltage-current characteristics. The experimental results con- firm the theoretical predictions of resistances in different configurations, reinforcing fundamental concepts in circuit theory.
